Folnir Eagle's Patron

Flying, Trample.
This card costs {x} less to cast for each card you
own in exile.
Instants, sorceries, and lands in your graveyard
have fortell. (The fortell cost is equal to that
card's mana value.)
Whenever you fortell a card from your
graveyard, Folnir Eagle's Patron gets +1/+1 until
end of turn, and draw and discard a card.
